Le procédé comprend les étapes suivantes : un équipement utilisateur (EU), en mode DRX, détecte si un événement de maintien d'état actif ou de passage à l'état actif se produit ; lorsque l'événement est détecté, l'EU envoie à une station de base des informations d'indication de sortie de mode DRX et d'état de maintien d'état actif ou de passage à l'état actif ; et l'EU quitte le mode DRX et maintien l'état actif ou passe à l'état actif, et reçoit les données envoyées par la station de base. La solution technique de l'invention supprime les problèmes de retard de service ou d'interruption de transfert intercellulaire en mode DRX.
